BUILDING TILE.

, Application filed september 29, 1921. serial no.' 504,057.

To aZZ whom t may concern: t

Be it known that I, ALBERTH. ROETH, a citizen of the United States, and a resident of the city of New York, borough o'f the Bronx, in the county of Bronx and State of New York, have invented anew and Improved Building Tile, of which the following is a full, clear, and exact description.l

This invention relates toimprovements in building tiles, an object of the invention being to provide an interlocking tile priovided with both vertical and horizontal air spaces which will effectively prevent moisture from seeping through a Vwall.

A' further object is to provide building tiles which, `when arranged in tiers, will provide vertical and horizontal passages through the tiers and from the top to the bottom of a wall.

Still another object is to provide an intei-locking damp-resisting buildingl tile in which air spaces are provided between every mortar joint so that if the oiitside joint absorbs moisture, there is no danger of the moisture seeping'through the wall.

Vith these and other objects inview, the invention consists in certain novel features of construction, combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims. I

In the accompanying drawings- Figure l is a perspective View of one of my improved tiles.

Figure 2 is an end view showing two of the tiles` in super-imposed. relationship.

Figure 3 is a. fragmentary top plan view partly shown in section showing the Inanner in which the tiles interlock. Y

Referring in detail to the drawings, my

improved building tile comprises a pair of outside walls l and 2 and apair of inner walls 3 and 4. Integral webs 5 spaced from the ends of the walls connect the outer and inner walls.

the upper and loweredges of the .walls to provide horizontal air spaces such as6 when the tiles are arranged in super-imposed relationship'.

It will also be noted that the webs 5 are spaced a considerable distance apart to provide vertical air passages 7 between the inner and outer walls of the tile. The two inner Walls 3 and 4 are connected by integrai sich; as 8.

These webs terminate short of'l It will be seen that the webs8 terminate short of the upper edges of the inner walls and extend ap- Y preciably below the lower edges of `the inner walls. lItxis to be noted, however, that the distance'between the top of the Webs 8 and thevupper edges 'of the walls 3 and 4 isgreaterhanthe distance between the bottom of the. webs 8 and the bottoms of the walls 3 and 4. By virtue of this construction, an additional horizontal air space, such 65 as 9, is provided between the two innerwalls when the tiles are arranged one upon the4 other.. f Dove-tailed grooves are formed by"co acting recesses 10 in oneend of each'of the walls and 4.. These grooves interlock with tenons 11 at'the other ends of the walls 3 and 4 in an adjacent tile.

When the tiles are laidthe mortar'is placed upon the upper surfaces of vall of the walls as indicated at 12 and is also applied to the ends of all of the walls as indic-atedat 13 so that the tiles are completely encircled by four spaced mota-r ,joints. Each mortar joint is separated from 'adljacent joints by bothA horizontal and ver-fUA tical yair spaces, hereinbefore described, and there is but slight chance of moisture seep ing from one joint to the' next one.'

Although I have shown and described a `building tile formed of a single piece ofy material by any approved and well known method, it will be apparent that interlocking building blocks might embody the. same novel features as the illustrated tile. Various slight changes and alterations might be madein the general form andl arrangement of the parts described', without departing from the invention and hence I do not wish to limit `myself'to precise details set 95 forth, but shall consider myself at'liberty to make such slight changes and alterations as fairly fall within the spirit and scope of the appended claims. .f

What I claim is .p

LA building tile, comprising a pair of inner walls connected byv webs, a pair of outer walls connected to the inner walls by webs, the webs being spaced from the ends and terminating short of the upper and 1o5 lower edges of the Walls, said inner walls having grooves formed in their inner faces at one end forming a. dovetaii groove, and grooves formed-in their outer faces at the other end forming a tenon. e

2. A building tile, comprising' a pair of inner Walls spaced apart and connected by Webs, a :pair of outer walls connected to the inner walls byA Webs, said inner Walls pro- 5 jecting beyond the outer walls at one end and having grooves eut in their outer faces forming a tenon on the extended end and 2dnd forming a dovetail slot, the said webs being spaced fromy the ends of the Walls and terminating shortof the 4upper and lower edges ofithe walls providing horizontal air passages.
